In addition to the long list of other updates we’re seeing today in wake of Mountain Lion’s release, Apple has pushed out a new version of iTunes U. iTunes U, as you may know, is an iPhone/iPad app that gives users free access to college courses and other valuable resources.

Among the program’s new features is a new note-taking option, which allows you to easily take notes while watching or listening to a lecture. Keep reading for a rundown of all the changes…

From the App Store description:

“iTunes U 1.2 now makes it easy to take notes while watching or listening to a lecture. This update also adds the ability to search within posts, assignments, notes, and materials — from any of your subscribed courses — using the improved Search feature in iTunes U. It is also now simple to share your favorite courses with friends using Twitter, Mail, and Messages.”

iTunes U contains complete college courses from some of the world’s leading universities including Yale, Stanford, MIT, and Oxford. And, as Apple announced on its conference call yesterday, 750 new courses were just added.

If you’d like to check out iTunes U for yourself, you can find it for free in the App Store.
